Phylogenetic Analysis of Astrovirus and Kobuvirus in Korean Dogs

Astroviruses and kobuviruses are frequently found in mammalian feces, including that of humans. The present study examined fecal samples from 91 Korean dogs suffering from diarrhea. Canine astroviruses (CAstVs) and canine kobuviruses (CKoVs) were identified in 2 (2.1%) and 46 (50.6%) dogs, respectiv...

Description
Summary:Astroviruses and kobuviruses are frequently found in mammalian feces, including that of humans. The present study examined fecal samples from 91 Korean dogs suffering from diarrhea. Canine astroviruses (CAstVs) and canine kobuviruses (CKoVs) were identified in 2 (2.1%) and 46 (50.6%) dogs, respectively. Nucleotide sequence analysis coupled with phylogenetic analysis using the neighbor-joining method showed that CAstVs clustered into four genetically diverse groups. Two Korean CAstVs belonged to group 2 alongside strains isolated in Italy and France. Twelve of the Korean CKoVs belonged to a single clade, along with strain UK003 identified in the UK and six CKoVs identified in the USA. Thus, the results suggest that the Korean strain of CAstV is closely related to strains isolated in Europe. Surely, CKoV in South Korea could identify the circulation among dogs population.
